A female giant anteater named Armani at the LEO Zoological Conservation Center in Greenwich, Conn., gave birth to baby girl Alice in August, followed by the surprise April birth of baby boy Archie. That poses a biological mystery because Armani and her mate were separated after the first birth. It's possible that Archie's birth was the result of delayed implantation, although that's never been recorded in the species and would be surprising immediately after giving birth. More likely, the pair somehow gained access to each other, although staff at the center don't believe that's possible.
